      [Coverage] Enable merging coverage data from swarming. · 6e401f20
      machenbach authored
      This adds a function to the sancov_merger that merges the
      output files of one swarming shard in parallel. This will
      be called from the infrastructure when collecting/merging
      swarming results.
      
      The tool will be called subsequently for each shard. On
      the first call, the target dir will be empty and the sancov
      files will just be moved.

      [coverage] Enable sanitizer coverage. · 33ffced5
      machenbach authored
      This adds sanitizer-coverage compilation, test-runner
      features and post processing.
      
      Sanitizer coverage is expected to be used together with
      asan.
      
      During test runner execution, the produced sancov files
      are disambiguated and match the pattern:
      <executable name>.test.<test id>.sancov.
      
      Two additional scripts are added for merging raw sancov
      files and for generating json data containing all
      instrumented lines + all covered lines from merged sancov
      files. Both scripts use multiprocessing for speed.
      
      The json data will later be uploaded to google storage
      for further use, e.g. to show coverage data in rietveld.
